Stainless Stainless Steel

"Stainless" means stain-resistant, not stain-proof. In kitchen use, the steel can still discolour or pit if exposed to acidic environments — citrus, vinegar, or salt water — for extended periods. Wash and wipe dry after every use, and avoid leaving the blade soaking in water. With basic care, a stainless knife is very low-maintenance and a great everyday choice.

German Steel 독일강

Hardness ? Rockwell C Hardness(HRC) measures how resistant a steel is to permanent deformation. For kitchen knives:

55–58 HRC — Soft. Easy to sharpen and forgiving of rough use, but dulls faster. Typical of most German knives.
59–61 HRC — Balanced. Good edge retention with manageable sharpening. Common in mid-range Japanese knives.
62–64 HRC — Hard. Excellent edge retention, holds a very fine edge. Requires more care and a fine stone to sharpen.
65+ HRC — Very hard. Exceptional edge longevity but more brittle — more prone to chipping if used roughly.

Higher is not always better — it depends on how you use and maintain your knife.

주방용 칼과 식기류에 널리 쓰이는 독일강 1.4116은 크롬, 몰리브덴, 바나듐 등 특정 합금 조성 덕분에 내식성, 내구성, 연마 용이성 면에서 훌륭한 균형을 제공합니다. 다만 다른 하이엔드 나이프 강재에 비해 탄소 함량이 상대적으로 낮아 일부 주방용 칼 용도에는 적합하지 않을 수 있음을 유의해야 합니다. 낮은 탄소 함량은 강재가 도달할 수 있는 최대 경도를 제한하며, 이는 곧 칼의 절단력 유지력에 영향을 미칩니다. 즉, 1.4116 강재 나이프는 날카로운 날을 세울 수 있고 녹에도 강하지만, 고탄소강 나이프보다 더 자주 연마해야 할 수 있습니다.
Composition

German Steel Element Composition

Compare with
    German Steel
    14.0% 10.5% 7.0% 3.5% 0
    C Carbon 0.5%
    Primary hardening element. Raises hardness and wear resistance — but too much increases brittleness and corrosion susceptibility. As a reference: German 1.4112 (~0.5%) sits at the low end; VG-10 (~1.0%) is a common mid-range; SG2 (1.25–1.45%) and ZDP-189 (~3.0%) represent high and extreme ends respectively.
    C
    0.5%
    Cr Chromium 14.0%
    Raises corrosion resistance; 13%+ qualifies steel as stainless. Also improves hardenability and wear resistance. In kitchen use, higher chromium levels contribute to a slight drag or sticking sensation when cutting — a trade-off for the rust resistance it provides.
    Cr
    14.0%
    V Vanadium 0.1%
    Forms extremely hard carbides for superior edge retention. Also refines grain structure, improving toughness.
    V
    0.1%
    Mo Molybdenum 0.5%
    Improves hardenability and toughness. Boosts corrosion resistance and helps the steel hold hardness under heat.
    Mo
    0.5%
    Mn Manganese 1.0%
    Aids hardenability and strength. Acts as a deoxidiser during smelting. Excess can reduce toughness.
    Mn
    1.0%
    Si Silicon 0.5%
    Strengthens the steel matrix and acts as a deoxidiser. Improves hardness and resistance to oxidation.
    Si
    0.5%
    P Phosphorus 0.02%
    Impurity from the smelting process. Even small amounts cause brittleness — steelmakers keep this as low as possible.
    P
    0.02%
    S Sulfur 0.01%
    Impurity that reduces toughness and promotes brittleness. Intentionally added only in free-machining steels.
